Resize nova instances on RDO Liberty

Per http://funcptr.net/2014/09/29/openstack-resizing-of-instances/
During the resize process, the node where the instance is currently
running will use SSH to connect to another compute node where the re-sized
instance will live, and copy over the instance and associated files.
Actually, there is an option to change this behavior and perform resize instance on the same compute node .
View :- http://www.madorn.com/resize-on-single-compute.html#.Vgb1wrNRpFB
Just one notice it requires restart all nova services on Controller and
openstack-nova-compute on Compute Node.
Posting bellow presumes that there are at least 2 Compute nodes :-
compute01
compute02
